This document provides an introduction to cloud computing, including definitions of cloud, cloud computing, and cloud computing architecture. It describes the basic concepts of deployment models (public, private, hybrid, and community clouds) and service models (IaaS, PaaS, and SaaS). Infrastructure as a Service (IaaS) provides access to computing infrastructure resources, Platform as a Service (PaaS) provides development and deployment platforms, and Software as a Service (SaaS) provides access to software applications. The document notes advantages of cloud computing like lower costs and improved performance, as well as disadvantages like requiring internet access and potential security and performance issues.

3. INTRODUCTIONINTRODUCTION
Cloud Computing provides us a means by which we can
access the applications as utilities, over the Internet. It
allows us to create, configure, and customize
applications online.

4. WHAT IS CLOUD?WHAT IS CLOUD?
The term Cloud refers to a Network or Internet.
In other words, we can say that Cloud is something,
which is present at remote location.
Cloud can provide services over network, i.e.,
on public networks or on private networks.

5. WHAT IS CLOUD COMPUTING?WHAT IS CLOUD COMPUTING?
Cloud Computing refers to manipulating,
configuring, and accessing the applications online.
It offers online data storage, infrastructure and application.

7. BASIC CONCEPTSBASIC CONCEPTS
There are certain services and models working behind the
scene making the cloud computing feasible and accessible to
end users. Following are the working models for cloud
computing:
1. Deployment Models1. Deployment Models
2. Service Models2. Service Models

8. DEPLOYMENT MODELSDEPLOYMENT MODELS
Deployment models define the type of access to the
cloud, i.e., how the cloud is located? Cloud can have any
of the four types of access: Public, Private, Hybrid and
Community.

10. PUBLIC CLOUDPUBLIC CLOUD : The Public Cloud allows systems and
services to be easily accessible to the general public.
PRIVATE CLOUDPRIVATE CLOUD : The Private Cloud allows systems and
services to be accessible within an organization.
COMMUNITY CLOUDCOMMUNITY CLOUD : The Community Cloud allows
systems and services to be accessible by group of organizations.
HYBRID CLOUDHYBRID CLOUD : The Hybrid Cloud is mixture of public and
private cloud.

11. SERVICE MODELSSERVICE MODELS
Service Models are the reference models on which the
Cloud Computing is based. These can be categorized
into three basic service models as listed below:

12. 1.1.Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)2. Platform as a Service (PaaS)
3. Software as a Service (SaaS)3. Software as a Service (SaaS)

13. INFRASTRUCTURE AS A SERVICE (IaaS)INFRASTRUCTURE AS A SERVICE (IaaS)
IaaS is the delivery of technology infrastructure as an on
demand scalable service.
IaaS provides access to fundamental resources such as
physical machines, virtual machines, virtual storage, etc.

14. IaaS EXAMPLESIaaS EXAMPLES

15. PLATFORM AS A SERVICE (PAAS)PLATFORM AS A SERVICE (PAAS)
PaaS provides the runtime environment for applications,
development & deployment tools, etc.
PaaS provides all of the facilities required to support the
complete life cycle of building and delivering web
applications and services entirely from the Internet.

16. PaaS EXAMPLESPaaS EXAMPLES

17. SOFTWARE AS A SERVICE (SaaS)SOFTWARE AS A SERVICE (SaaS)
SaaS model allows to use software applications as a service
to end users.
SaaS is a software delivery methodology that provides
licensed multi-tenant access to software and its functions
remotely as a Web-based service.
